Abstract: A well plate assembly including a base plate and vials. The well plate assembly includes a base plate having a bottom, a perimeter having opposing edges, and a plurality of protrusions extending from the bottom spaced apart from each other to form a plurality of compartments sized and configured for releasably holding vials. Each of the compartments includes a convoluted anti-rotation feature recessed into the bottom. The vials each have a bottom wall, a first side wall segment extending upwardly from the bottom wall, and a second side wall segment extending from the first side wall segment to an open top. The first side wall segment includes at least one spline designed to mate with the convoluted anti-rotation feature to prevent rotation of the vials when a torque is applied, for example, during capping or de-capping operations.

Abstract: A two-piece seal vial assembly. The first piece is a vial defining an aperture adapted to contain a liquid. The vial has a base, a crown disposed opposite the base, and an upright side wall extending from the base to the crown and including a tapered inner diameter and a flange located proximate the crown. The second piece is a seal top defining an opening that runs through the length of the seal top. The seal top has a top portion providing a neck finish and, when the seal top and the vial are assembled, a snap groove releasably receiving the flange of the vial and a tapered portion that frictionally engages the tapered inner diameter of the vial. Although not one of the two main components of the assembly, a cap may be included to releasably engage the neck finish of the seal top to close the seal top.

Abstract: An adhesive sealing film for a multi-well plate, said sealing film comprising a polymeric film coated on one side with a pattern formed from adhesive, wherein the adhesive pattern does not cover areas of the sealing film that correspond to the wells in said multi-well plate.

Abstract: A versatile vial and plug combination forming a securely sealed closure of the vial. The combination includes a vial with (a) a head with an inner diameter (ID) and an outer diameter (OD); (b) a body with an ID and an OD substantially equal to those of the head; and (c) a neck having an ID less than the ID, and an OD less than the OD, of the head and body, providing a recessed robotic arm pick up area adapted for engagement by automatic equipment. The combination also includes a resilient plug with (a) an inwardly tapered base, (b) a top flange, and (c) a body having an OD that corresponds to or is only slightly greater than the ID of the vial, assuring an interference fit between the plug and the vial, thereby sealing the plug inside the vial upon insertion of the plug in the vial.

Abstract: A vial plate includes a base plate having protrusions spaced from each other to form compartments for supporting vials and openings which allow the flow of liquids or gases to heat or cool the vials. The vial plate may have a cover and use a multi-tiered structure having one or more spacers which attach to the base plate, each other, or the cover to vary the height of the vial plate for accommodating vials of different sizes. The vial plate does not float in water, can accommodate vials containing volatile solvents, and can support individual vials.

Abstract: A crimp top seal which can be applied to a variety of different containers. Circumferentially displaced points or lines of contact between the crimp top seal and the container at axially displaced positions provide self-alignment and secure retention of the crimp top seal on the container. The resilient crimp top seal includes a top member, angular locking ribs, and a crimp ring or lugs--all of which engage the neck finish on the container. The inner diameter of the skirt of the crimp top seal, the angle of the locking ribs, and the crimp ring or lugs provide the multiple, axially displaced lines of contact and allow the crimp top seal to engage a variety of containers.

Circumferentially displaced points or lines of contact between the crimp top seal and the container at axially displaced positions provide self-alignment and secure retention of the crimp top seal on the container. The resilient crimp top seal includes a top member, a skirt extending down from the perimeter of the top member, angular locking ribs, and a crimp ring--all of which engage the neck finish on the container. A plurality of reinforcing members are also provided on the inner surface of the skirt. The inner diameter of the skirt of the crimp top seal, the angle of the locking ribs, and the crimp ring provides the multiple, axially displaced lines of contact and allow the crimp top seal to engage a variety of containers.

Abstract: A container for use in retaining laboratory or hospital samples with an upwardly biased and centered inner container or insert and a spring applicable for use with such a container.

Abstract: A cap closure having a top member with a center opening, a dependent skirt and a liner. The liner has a central raised portion, which may be concave, which mates with the center opening in the top member by an interference fit, thus retaining the liner in the center opening and under the top member.

Abstract: The present invention comprises a capsule holder for loosely holding a capsule, such as a capsule containing a pharmaceutical agent, during fluid immersion testing. A plurality of resilient gripping fingers surround a space sufficiently large to receive and retain the capsule. The fingers are connected at one end by connecting arms and may be resiliently deflected outwardly to permit insertion of the capsule into the retaining space.
